Fair enough. I ran 1.51-1.52ish laptimes so I'm for sure leaving a bunch of speed on the table. I'll try braking less into that turn next weekend

I think our fastest time in the Charade was 1:50.x, so I sincerely hope you do, unless a open diffed 200K mile LeMons car on 7 inch wide street tires is faster.

I think the Daihatsu has been on the same set of Star Specs for 3 races, though the last 2 were early DNFs. We have enough meat left over to do the 12 hour night race at Streets of Willow next month.


Note that its a 1500lb car with 120hp and proper camber/toe/caster so it doesn't needlessly chew through tires.

Get the lightest possible helmet for auto racing, the strain a cheap and heavy helmet puts on your neck is worlds apart from a Kevlar or carbon fiber helmet weighing 1/3 - 1/2 as much. I love my HJC AR10 (original), its a great helmet and not the worst thing to work on by putting a radio in, and you can mix and match pads (XXS to M is one shell size, L to XXL is another), I run L headcap and XL cheek pads in mine. Stilo helmets do not have removable pads and are assembled with a glue similar to superglue and they tear like crazy if you dismantle the fabric sections. The HJC Si helmets are alright, but lose the removable cheekpads and hence are annoying to own.


HJC makes the best cost/value helmets, Pyrotect is the worst. Bell is a terrible value for a gilded Pyrotect, Arai is beyond expensive and not amazing. Impact! got in deep poo poo for making their own SFI stickers, bypassing the SFI Foundation's licensing fees and supposedly their certification system. A very poor decision and not one that should be forgotten anytime soon. Simpson is also not that great for performance/value. Peltor's helmets are nice, but expensive.

Is kind of a red flag, as selling a car without smog is illegal in this state. I kind of wonder if it will fail.

Yes, since cars in California (in smog counties) are required to have a local passing smog test when sold, and it is only valid for 90 days since the test. This person either doesn't know that (its not complicated so somewhat doubtful for an enthusiast car type), or they are just playing it off as a minor detail.

You can do whatever the gently caress you want* after a stock catalytic converter or a CARB approved replacement. They say CE #### or something on the cat if its California legal, otherwise a '49 state' or off-road cat would be at least a visual inspection issue, and possibly an issue for actual tailpipe emissions.

Are you interested in wheel-to-wheel racing and wrenching? You could check out ChumpCar. About a year ago I was in the same spot as you, looking for a cheap, fun car to wrench on and take to track days. I eventually gave up because everything in my price range was salvage titled or otherwise falling apart. ChumpCar's price limit is $500, not including safety equipment, so you basically want your car to be falling apart! Having 4-6 people really helps keep costs down, too. Each event is a 7-24 hour endurance race, and it's popular nation-wide. Perfect!

I'm going to be volunteering to work corner stations this summer, and trying to get a team together this fall/winter to participate next year.

Anyway, something to think about.

Yeah sorry, I should have been more clear. A better way of phrasing: if you were taking your modern bone-stock car to the track for a single day on r-compounds instead of your more focused racing/sports cars, what level of prep would you bother with?

Bleed with good fluid, and make sure the pads have plenty of meat left. Add camber if you can, if not expect the outside of the tires to be destroyed pretty quickly. Heavy Mac-strut FWD cars without proper camber destroy tires in short order.


Have fun, change the brake fluid!

I think it's a thing that I like having some pride in my car a little more than some of the (totally admitted) heaps I've seen at Lemons/Chump events (no offense intended, it's just not my bag).

I think a lot of us would like that as an ideal, but good year-round weather and decent transportation network, and ability to reasonably acces the car and work on it is pretty rare. I could store my racecar on my parents property in my workshop, but it wouldn't be easy to get here with the transportation network, which stops 15 miles away.

At the race you drove, absolutely a badly setup shitpile run by idiots. We ran 2:40 at Thunderhill that race, the next race was a 2:19. A few races later we ran a 1:55.0 at Laguna Seca, which is faster than stock 986 Boxster S. Not bad for 110hp on 7" street tires.

Exactly. I had to learn these things, guess about suspension settings, and hope 200K mile engines would hold together when taken 800RPM over their factory fuel cuts for hours at a time. Its been an awesome trip so far, and although the Charade is really as developed as it could be running one of the tightest racing budgets in the two series, I'm still not really done with racing. In fact, I start a job on Monday selling communications systems to LeMons/Chumpcar teams, so who knows what my role in that racing will be.

I don't run Chumpcar so I'm not familiar with the fields. While I realize it's not for everyone (especially SERIOUS RACE CAR DRIVERS), I actually love the enforced zaniness and slew of bizarre builds at Lemons.

We never really got into the zany feel of LeMons, Chumpcar is really our bag, but we aren't competitive in it. We're hoping the general reliability of the car gets us through the 24 hour race at Buttonwillow next month, while we brainstorm our next car.


I like the really exotic builds in LeMons a lot, but I'm more excited in a motor cycle engine in a Metro than an old Cessna body on a Toyota van. LeMons has a lot of different things to offer, and some teams like Eyesore Racing can fill a lot of the niches at the same time, where our zaniness stopped past "we're seriousracing a Daihatsu." Its so much just to do that bit, we never really got into a theme beyond making it look like a touring car, and even then function was still more important with that.

Hotter than hell at Buttonwillow this weekend, I didn't get many pics or video as I was fixing broken poo poo most of the weekend.

We we pitted 1 stop away from Bloot so that was cool to meet him and see the awesome M1 CRX. Got a shot of him before the start of the race:


Here we are getting ready


Car: 87 535i with an E34 M30B35 motor, Getrag 260 and 4.10LSD

On track it handles adequately and has a lot of power and puts it down well, but it inspires very little confidence.

This is my first race with this team and I didn't really have a hand in car prep except for building the bottom end in the last few weeks and then installing it in a rush with no time to check anything else because of inadequate planning.

The first day we were battling undiagnosed fuel starvation, turns out the transfer pump was dying which we solved Saturday night by bypassing the pump.

The first thing to break was about 2 hours into the race and it was the front pulley falling off on track. The bolts must not have been tightened properly (this will become a theme). This caused the front harmonic balancer to cause a misfire and almost fall off so I came in and replaced that. Luckily we had a spare. One bolt broke off in the crank snout so we chased the threads in the open holes, installed 7 of 8 bolts and went out again.

A few hours later the team captain got a black flag and then the car wouldn't start in the penalty box. We pushed it into pits and found the alternator not charging. I traced it to a nut that was improperly tightened that had come loose and fallen off holding the positive charging wire to the back of the alternator.

I think there was some more issues Saturday but I cant remember. In addition, I was adding water to the radiator almost every pit because the radiator was woefully inadequate for the 105 degree ambient heat. When I was driving I had to cruise around in 5th gear every other lap as the car was overheating.

That night we bypassed the pump.

Sunday the car ran great in the morning, until there was some contact damage to the left rear fender that had pushed into the tire and was shaving down the sidewall. We got a chain puller on that and were able to pull that out and keep racing. Then the car came in completely dead. It turns out the main fuel pump died, probably from having been starved so much the day before. We replaced it with a pump from one of the other BMW E28's that had died earlier in the day and kept racing.

Then the car did okay until the 2nd to last lap when the motor decided to give up and spin a rod bearing. I'm convinced that because we have a stock radiator and no oil cooler, (and no oil temp gauge) that the oil just got too hot and thin and the motor let go.

I'm kind of discouraged, mostly with team dynamics and prep, but at least I got 3 stints in and the car ran most of the time.
I'd really like to build my _own_ car next and prepare it properly to survive an endurance race.

Miss the Daihatsu? We miss you!

I was at an event at Thunderhill on monday. I ran 7 20min sessions. My arms and neck hurt all week. Ran mid-low 2:20's though, not bad for my first dry track day though.

This may have been stated already but... Thunderhill is in the process of expanding and they had all kinds of earth-moving going on. It's already a fairly long track so it'll be cool to watch the 25hrs of Thunderhill or something on a 4.5 mile course. And they'll have the ability to have 2 separate events east/west too.

I'm considering leaving the Charade disassembled and actually buy this extant rally car and make it work in NASA, Rally America, and LeMons/Chumpcar. It might be EC in Chumpcar, and penalized heavily in LeMons, but it'd be cool to concentrate time and resources on a single car.

Multi-point harnesses are pretty useless without the crotch strap, and unless you have the hole in the seat pan (never put it in front of the seat), its probably dangerous. A CG-Lock and the stock seatbelt is a decent bet. This is why lots of dedicated track cars have racing seats with the aforementioned crotch strap hole.

I thought this was a good article about WRL: http://sopwithmotorsports.com/blog/...torsports?.html

I enjoyed it, especially the hard truths about SCCA's own control issues, really could have done more than deify WRL at the expense of intentionally never mentioning Chumpcar. LeMons is a great stepping stone to get cars built and masses of people in them, Chumpcar is another stepping stone towards making the racing more of a centerpoint, and WRL takes that idea further. It would have been far better in that article to use that as a progression rather than the snub. Sure, Chumpcar is and has been entirely mismanaged with regards to internal politics and respect towards staff, and WRL really seems to be the next iteration of the idea, but really it is far more positive than that article makes it seem.


note: I am involved tangentially with WRL, and I'm definitely not saying that it is any less awesome than it is, but more that snubbing Chumpcar is and never was the goal, though some people seem to not understand that part fully.

What do pro race series use to be legal?

To be legal in the eyes of the FCC, a business (race team) obtain a license to operate commerical band equipment, usually geographically locked at the location noted in the application, usually pretty easy to obtain with low power handhelds and derated mobile radios use in racing. Then you just use the radios at tracks* and watch for stepping on others. Real teams and sanctioning bodies coordinate frequency use and can move around inside their licensed frequencies to get everyone in there, or at least on different CTCSS/CDCSS tone or whatever the equivalent is for their specific DMR system.

The other way is to rent/lease radios and piggyback on the vendor's licences, which is the 'normal' way its done to circumvent the licensing hoops. Sanctioning bodies themselves do this, as well.


*Note that this can be operating outside the license's geographical limitations, unless you got some serious talent working on your applications and know what tracks you will be at...


edit: Its a gigantic shitshow and it really only works when everyone uses a single vendor who has an exclusive deal with the sanctioning body. Circle/oval track racing tends to have bans on two way radios, though sometimes has one way spotter communications with a Raceiver or similar receive only setup. LeMons/ChumpCar/WRL is a huge loving shitfest radio-wise and people run garbage radios all over bands that get the FCC or local emergency response really interested in the event. Its far far far worse now with VFO mode enabled "Commercial" garbage like the Baofeng UV5R and its ilk.

I wouldn't continue to wear a motorcycle helmet in a car when I could buy a properly rated one. You'll have to anyway if you progress past the HPDE/auto-x level. Motorcycle helmets aren't designed for cage/windshield hits, nor certified fire retardant materials/construction. Oddly enough, there are some dual-certification helmets, they just aren't common or particularly nice.

I guess this is the best place to ask, but I'm looking for the best rallycross tire in near stock size (185-60-14) for my Stock-4WD class 323 GTX. I've seen the General Altimaxx Arctic mentioned as the one of the best options, really just looking for the best place to buy them. I'm in sandy (DG soil) with little actual gravel content, and would like some streetability since there's lots of well groomed dirt roads around. I'm in sunny California in the coastal mountains so they'll never see ice or snow, or likely even sub 50degF pavement.

Also, what is a decent street/track tire for a 15x6" wheel? I have 195 tires on there looking pretty square, so probably 195/55 or 205/50? They're 2002-sih Lancer OZ wheels. Last time I looked was before the UTQG 200-treadwear wars!
